Kalliopi Karatzi, Victoria G. Rontoyanni, Dr. Athanase D. Protogerou and colleagues at the Harokopio University in Athens recruited 17 healthy, non-smoking, men with a median age of 28 and a normal body mass index.

They consumed, on three separate occasions, at least one week apart: two-thirds of a pint of beer, the same amount of non-alcoholic beer and a vodka drink with the same amount of alcohol as in the beer.
